基于位置信息的无线传感器网络路由协议的改进

摘要

作为一种短距离低功耗的通信技术,ZigBee广泛应用在各种无线传感器网络中.随着物联网的发展,ZigBee中经典的AVOD路由协议在节能、安全性和稳定性方面暴露出了较大的缺陷.针对这些缺陷,该文提出了基于GPS模块提供的位置信息对ZigBee路由算法进行改进,根据传感器的位置信息控制传感器之间的洪泛路由,有效地降低系统的功耗,同时动态调整传感器发射信号的功率,降低功耗的同时保证系统的安全性和稳定性.%As a short-range low-power communication technology, ZigBee is widely used in a va-riety of wireless sensor networks. With the development of Internet of things, the classic AVOD routing protocol in ZigBee has exposed big flaws in energy saving, security and stability. In view of these de-fects, in this paper, the improvement of ZigBee routing algorithm based on the location information pro-vided by GPS module and the control of the flood routing between the sensors according to the position in-formation of the sensors are proposed, so as to effectively reduce the power consumption of the system and adjust the sensor transmitting signal power. Thus, power consumption is reduced while ensuring system security and stability.
